IMPROVEMENT IN MACHINES FOR MAKING METALLIC SPOOLS.

I 'Specilieatiou forming part of Letters Patent No. 210,088, dated November 19, 1878; application filed' To all whom it/)nay concern:

Be it known tha-tl, LATHAM BRIGHTMAN, of Cleveland, county of Cuyahoga., State of Ohio, have invented or discovered a new and useful Improvement in Metallic -Spools and their Mamifacture; and I do-hereb'y decla-re the vfollowing to he a full, clear, concise, and

'v exact description thereofreterence being had to the accompanying drawing, makiijig a part of this spccilieation, in whieh-likeletters indicating like parts- Y 1 Figure l isA a perspective view of my im- Aproved machine for making metallic spools. Fig. 2 1s a top-plan view of the same drawn to ,a reduced scale. Figs. 3 and 4 are detached p la-n views, drawn to a scale larger than Fig.

l, showing more fullythe operation ofthe machine upon the spool. Figs. 5, 6, 7, and S arev enlarged detached views of parts of the spool, illustrative of steps in its manufacture; and Fig. f) is a perspective view of a spool as made `on my'improved machine.

vIn preparing wire for use on self-binding harvesters it has been found convenient to wind such wires in continuous 'lines upon spools of suitable construction, such spools beingarranged on the binding device of the harvester in such way that the wire may be unwound therefrom as required.

My present improvement relates to the machine forthe manufacture of metallic spools suitable for this purpose.

In the drawings, H, Fig. 5, represents a sheet-metal plate or blank. shcared orstamped t0 ,the proper form and size for formingthe` shaft or barrel H of the spool. I prefer to punch one or more small holes, h, in this blank II, i'n which the end of the wire may be fastened preparatory to winding the spool. l I also clip'the corners hl a little, and, if desired,

- notches 71.2 may be cnt from the edges forming the ends of the barrel H', sothat the blank being .bent `to cylindrical form, as in Fig. 8,

the ends of such cylinder or barrel may be tapered somewhat, as at l.

The disks or heads of the spool K are cut circular, by preference, and one or more small holes, le', made in one-or both disks for fastening" the vend of the wire.' Central holes 7c are also made, having, by preference, 'a diam'- eter a little less than the full diameter of the August 26, 1878,

barrel HI', but large enough to allow the disks K to be slipped onto the tapered ends of the barrel, with the ends of thetapers l protruding somewhat. The holes k' may, however, he,

made large enough to allow the disks to more onto the full size of the ba'rrel; but I prefer to have them t tightly thereon, so as to keep- .their places. These disks K are secured on the barrel H' by'bendiug or flan ging the protruding ends l of the barrel against the outer faces of the disks, as seen in Fig-9.

I make use of the following-descrbed appa-1 I ratus for performing this last-mentioned fla-nging operation: In the drawing, A 'represents the ma ln frame or bed-plate,- which may bc supported in any suit-ableway. On the opposite ends of .this frame are 1nounted,in suitable bcarin gs, shaft-s a, a', which are driven bythe spur-gear wheels B B and crank-pinion b'. Other suitable driving mechanism may, however, be employed sets or puneh'esare actuated by the shaftsa-a y I on their respective sides as folloivsz- Frein each of thel blocks c c' two guide or slide bars,

d d d' d', extend back to or 'against wipersor eceen'trics 'it z" i on` their respect-ive shafts a a'. In thus extending back these guides 'or bars d d pass through suitably-shaped boxes or bearingsv in the cross blocks or beams m, so that while the bars d d' andblocks e c are kept in place, they are yetfree to 4mov-'e longi-` tudinally in such` bearings, and when the.

wipers 'i i press Aagainst; the adjacent ends of the guide-bars d d the blocks e ev will be carried forward or toward each other. -In order to` carry theseblocks backward again, I arrange 'levers or swinging bars g gl outside of. 4the shafts aa', and adjacent t0 or so as to be operated byv thewipers i'. `Thcsfe 'levers arel pivoted at thei1` lower ends to cross-rods '(12, andat their upper ends they are connected y rods y y' to vposts ff', which extend up from theblocks ,c e'. As the wipers t' z" are turned to the outside of their respective 'shafts they will pfress Arespectively against the levers g gl, lnovingfor swinging'them outward, and

Vthereby''drawing the blocks e c' back orawayfrom each "otler.

The sets or punches u 'n' are made slightly tapering toward the point, and with .Shoalders 'c o' at or near the base of each, so that i the points of `thepunches may enter the tapered ends of the barrel H' and open them out,

' i while the shoulders ce' will flange or bend such ends against the outside of the disks K.

These punches or sets are, arranged to operate througlropenings in the blocks ec', They are carried by'sterns or guidc-barso o, which extend back through suitable bearings` in the.

' beams m to or against-eccentries or wipers r 1" on tlie'shafts a. a.' As' these wipers -press yagainst the adjacent endsof the stems o othe" punches or sets will be carried forward or to- `or sets n n'are drawn back along w-ithl the blocks ce', the blocks engaging' shoulders o2 on the stems o o'. p Y

An anvil-block, D -D','- for holding the spool to be operated on, is arranged inline between the blocks e e' and 'sets n 'n'. It 'is made in twoparts, as shown, and the parts hinged to.

gether in any 'suitableivayn Ineach of these parts D D', and in line with the punchesor sets n n', is a concave or haltcylindrical groove,

A u u', in' which the barrel II' of the spool rests.

The lengt-h of this block D D' is equal to the desired length of the spool between thedisk's K.

A hook, j, is pivoted to the part D, and as -rangedto'hook onto a stud or pin, j', on the other part, D', and thus hold the two parts together. Springs 'or clips v o are arranged one on each end of the part D', so; that the'disks K may be slipped between them andthe ends' l of the block, and thus held in place upon the tapered ends l of the barrel until the blocks e e' advance vand force them on tight, and the fastening operation is completed.

l Prongs vor forks 'w fw aresecured tothe base Aer other convenient`part of the device, and a* -my hand.-

l y, I .2i-01088 BESTAVAILABLE Cop? they are so adjustedas to engage the disks K when the'part D' is raised or opened up, '(see Fig. 1,) an push the spool. out of its seat.

This operation may, however, be performed by h'and or in any convenient Way.

'If spools of dilferent lengths are required, the holding-block D D' may be removed along with its attached devices, and another substituted having a length equal'to the desired length ofspool; and in order then to ,secure the proper adjustment of pressure-blocks@ c" and sets im', the bars d d' and o o' may be replaced With others of the requisite length; or they may be lengthened or shortened, as re.

quired, by means of packers or linings and suitable extension-joints, as at d', Fig. 2.

'The operation of this device is as'follows:

The disks K and barrel H' heilig prepared as befre'described, the barrel'H' is laid in'the groove u,the part D' closed :down and se- 'cured, whilethe 'disksare so held on the tapered ends Z as to be clasped between the .clips or springs 'v c and the ends of the block.

The device is then put in motion. The blocks e ve'lare first crowdedvagainst the disks Kby the Wipers lii', thus forcing the disks tight' upon the ends of the barrel. vThe sets or punches n. u' then advance, and, entering the ends of the barrel, they flange or-bend such ends against the outer faces of the disks' and fasten them in place. 'The blocks c c' and punches n n' are then carried back, asbefore described, the upper part, D', of the anvil- `or holding-block is opened up, and the finished spoolremoved ,eitherbythe prongs w uf or in other convenient way.

I claim herein as my invention- 1v theeombination of a holdinglblock forjholding' the barrel while 'operated on, pressureblocks .`for forcing the heads'or. disks ;ot` the spool upon the barrel, and sets or punches for hanging the ends ,of the barrel against the disks, substantially as described.
